Best exposures for moral scrupulosity? Plz help

Hi! Does anyone experience guilt about doing exposures? Like if my OCD is right and now I’m going to get possessed or cause this terrible thing to happen it will be my fault. And also prove that my brain DOES have that power which is so scary. I just did an exposure and I feel so worried about my fears coming true and the people I love (& me) getting hurt because of it. How do you get past this? It feels like I shouldn’t do exposures because it’s selfish.

I'm really, really scared. I feel like my boyfriend and I went too far. We both belong to the same faith, and we've both committed from a young age to remain pure and chaste until marriage. And we've never had sex before, but we've talked a lot about it. And we've done things like laying on top of each other. Gently rubbing up against each other. He's kissed my chest. And I've send some pictures to him. Not nude pictures, but just ones that are a little revealing, and the guilt has been eating me alive. And of course, I know it's okay to feel sexual feelings, and it's good to have them and acknowledge them. They're vital feelings, and it's just us being human. It's a natural part of biology, and it's okay to be sexually attracted to one another, and to embrace that. It's something to be happy about. In our faith, we are cautioned against arousing sexual feelings in each other before marriage. And my boyfriend and I have absolutely done that, over and over again, when I've known better. Which makes me feel really guilty. Super guilty. I've struggled with scrupulosity for a long time. A really long time. And when I had a therapist who helped me to embrace my sexuality in a positive way, she really challenged my scrupulosity, and it helped me to attain a healthier view of the both myself and my standards, which is great. But in situations like this, I don't know if I'm dealing with scrupulous thoughts that are trying to make me fee feel guilty unnecessarily, or if I'm dealing with godly sorrow, like the kind of guilt that you feel so that you're urged to repent. And my boyfriend and I have kept an open dialogue about all of this since we started dating, and I think we've been communicating well, which is good. But we both agreed that last night, in particular, we really crossed the line, and I feel so guilty about it. We both agreed that this is a joint effort and that there's no blame to be put entirely on either one of us. My boyfriend has been really, really gentle about this subject, and I really appreciate his openness and honesty. But he doesn't see what we've done as anything to repent about. And even though he totally understands if I feel differently, I DO feel like we need to repent, both of us, not just me. He's open to hear any of my thoughts, even if they happened to be negative against him. And I appreciate that. But the guilt has been eating me alive. All the times I've made him moan on purpose because I like it. All the times I've let him talk so dirty to me. And the times I talked so dirty back to him. And I'm just comparing myself to other couples of our faith who may or may not have struggled, because obviously we're not the only ones to struggle. But we've done so much. We've talked so dirty to each other, and we're not even close to being engaged or anything. I just feel so filthy, and I feel ashamed for wanting to go further. A couple years ago, like I said, I had a therapist who really helped me to embrace my sexuality while also staying true to my faith. And I feel like I've really come a long way since then, but this feels different, because masturbation and embracing your own sexuality is different than teasing sex with another person. I just don't know how severe this really is. And I'm worried that I'll be reprimanded. I'm worried what would happen if my parents happened to find out. Not that I'm gonna tell them, but still, I'm really scared. I'd feel bad keeping this from them if it's really serious. I don't know what to do. I need to cry. My stomach hurts. I just feel all kinds of wrong.

I’m a Christian and I’m in my first relationship, often feeling guilty/uncomfortable with various things in relation to sexual purity. I’m struggling to know when things are OCD or genuine conviction. Any advice on how to know?
